ART ATTACHING HEELS.

Application filed October 24, 1921. Serial No. 509,820.

This invention relates to methods .of attaching shoe heels and is.concerned particularly tion type, atypical example of which is theconventional rubber half heel combined with a leather or: leatherboardbase section.

It-has heretofore been proposed to: attach heels the type-referred to ata single operation of the heel nailing machine, the leather base andrubber lift being assembled on the heel seat of a shoe and the load ofattaching nails being driven at a single blow Single nailed,multi-section heels have heretofore'been open to the drawback that whenit became time to repair the heel by removing-the rubber lift andattaching a new one the leather base section would drop off when therubber lift was removed because all the attachingnails passed throughwashers in the rubber lift, andconsequentlythey were all pulled out inthe act of removing the rubber lift. This happening was objectionable,not only because of to replace and attach the heel base before the newrubber heel'was applied but even more so because it spoiled the finishof the heel. edge and was liable to leave a crack at the junction of theheel base and the outer sole.

The object of the present invention is to overcome the difficultiesabove described and to provide a novel method of so attaching amulti-section, or composite, heel that the rubber lift may be removed,leaving the base attached to the shoe. For the accomplishment of thisobject the invention provides a method of. heel attaching whichcomprises pressing upon a shoe a heel base and a rubber top sectionhaving washers embedded therein, and driving simultaneously to the samedepth a plurality of attachingnails,

' some of which pass through said washers and some of which do not. Thismethod makes possible a virtually separate attachment of the basealthough all the attaching nails may be of the same length. In theillustrative example of the invention'hereinafter described part of thefastenings; viz,

the nails designed primarily to attach the heel base to the shoe, arelocated in portions of the rubber heel where there are no week withattaching heels of the multi-sec the extra time required.

nailslying atsubstantially the same depth in the rubber. As is wellknown, the nails have no substantial holding power in the .rubber in theabsence of washersor their equivalent and, therefore, when the rubberheel 1s removed only those nails will be pulled out which pass throughthe washers.

In aheel attached by themethod of this invention it may be consideredthat the at taching nails are divided into two groups, that is to say,those whose primary function it isvto secure the heel base permanentlyto the shoe and which are substantially effective only for that purpose,and those which serve the primary purpose of attachng the rubber liftand, incidentally, add security to the attachment of the base. The

nails of the first-mentioned group, at :least, may, advantageously,taper somewhat fromhead to point to afford additional holding power,although this is not essential to the invention. a

Other features and advantages of the invention will be understoodandappreciated' from reading the following detailed description inconnection'with the accompanying I drawings, in which Figure 1 is a viewpartly injperspective and partly in section of a composite heel attached to the heel end of a shoe;

Fig. 2 shows a. conventional type of heelmachine equipped to attachheelsin 'aceordance with the invention; and

Fig. 3 is an enlarged detail illustrating more clearly the relation ofthe elements at the end of the nail driving operation.

Referring now to the drawings, a composite heel is shown consisting of abase section 10, which may be made of leather,

leatherboard .or like material, and a rubber lift, or half heel, 12superposed upon the base 10. The heel consisting of thetwo sectionsabove described is located upon the heel end of the outersole '14 of theshoe and the whole assemblage'is secured together by nails 16 driventhrough and clinched in the innersole 18. v r

The usual washers 20 are embedded in the rubber heel section and slightindentations 22 may be provided on the tread face thereof to indicatethe points at which the base attaching nails are ts be err-vealThe'nails are preferably tapered from head to point,

as shown, and are all driven to the same depth, as clearly illustratedin Fig. 3. No Washersare located beneath the indentations .22 andconsequently the base attaching nails,

While they hold the base 10 securely to the shoe by reason of thefriction between them and the relatively rigid material of the base 10,and the tapered shape of the nails, are hot substantially effective insecuring the rubber section 12, the nails which pass through the washersbeing depended upon 7 ing' rubber back and forth upon the base,

which occurs to a detrimentaldegree each time the weight of the wearercomes upon a rubber heel of the washer type attached by relatively fewnails. 7 7

VVhen it is desired to remove the rubber lift 12 it may be pried ofi',pulling out thenails which ass through the washers 20,

while the rub er strips easily oil the heads of'the remaining nails,leaving the latter unmoved and leaving the base 10 undisturbed. Theprojecting heads of the last-mentioned nails may then either be clippedOR or the new rubberlift forced upon them, and the usual attaching nailsmay be driven to secure the new rubber section to the base.

Referring particularly to Fig. 3, 24 indicates an improved form of naildriver which is sharpened at the point '26 where it an gagesthe head ofthe nail 16. The pressure required to drive the nail is suflicient tocause the point 26 to indent the nail head,

and any sidewise bending of thenail in the soft substance of the rubber12 is effectually prevented. The-portion 28 of the driver is alsotapered toward the sharpened point, permitting the driver to enter thesubstance of the rubber lift 12 smoothlywithout lacerating the'rubber.This minimizes the defacement of the rubber lift by the driver,

the mark remaining after the driver is with drawn being insignificant.

It should be clearly understood that the word rubber, used herein inreferring to commonly used in the manufacture of cushion heels. Likewisethe word .leath'er, used in referring to the base section 10,

should be understood to include 'leatherboard and other equivalents, ofwhich such heel I bases are made.
